Today, it was announced that Android smartphones now account for 50% of the global smartphone market, making it the most popular smartphone network on the planet. Android was a distant fifth in smartphone platforms when it was launched in 2007, behind Apple’s iOS, Blackberry (RIM), Windows Mobile, and Symbian. With millions of Android devices in use and over 500,000 new Android devices installed every day, Android is the most common mobile operating system on the planet.
01: Gather the Tools: Java, Android SDK, Eclipse + ADT Plugin
Android can be developed on a PC, a Mac, or even a Linux desktop. More good news: all of the software you’ll need to build Android apps are available for free. To begin, go to the Oracle website and download and install the most recent version of Java SE. Next, go to the Android Developers portal and download the Android SDK (Software Development Kit).
02: Learn the Java Programming Language
The majority of Android apps are written in Java (though some are written in C++). For Android application creation, a strong command of Java is needed. The object-oriented programming style of Java is used for Android. In object-oriented programming, programmer components are broken down into bits that resemble “real-world” artifacts. In a video game for Android, for example.
03: Understand the Android Application Lifecycle
Even if you’ve written desktop or web applications before, it’s important to realize that writing smartphone apps is a totally different experience. The operating system handles other programmers and their goals with a desktop programmer. It’s up to you to code your Android app to deal with external events. As an example.
04: Learn the Android API
Although Android apps are written in the Java programming language, the Android API (application programming interface) expands the command set by adding completely new sets. You can write code that manages anything from the on-board camera and audio recording capability to Bluetooth connectivity and Wi-Fi connectivity, and much more, using Android packages (groups of classes).
05: Write your first Android Application!
Writing your first complete Android App developer can seem daunting, but the process will be easier and more pleasurable if you choose a topic that you enjoy. Write the app in several versions, beginning with the most basic features and gradually extending its functionality. Debug and test carefully along the way to ensure that your application works in all situations.
